This is a pretty niche case but my band sometimes puts on livestreams, for which I use an Atem Blackmagick and OBS with a plugin that automatically changes the camera input at random intervals. I use an old CC in one of the hdmi channels that has some random visuals streaming to it from the same laptop that we run the stream off of, which I bleed 50% with one of the other camera inputs for a fun little psychedelic effect. I’m sure there are other ways to achieve this without hardware, but it works for me/us and gives the old thing something to do. ::shrug::
